I have Windows 2003 domain. My plan is to deploy windows 2016 DC.
Here is my plan
Step 1- ) Install Windows 2012 R2 as member server ( Server A ) and prepare forest and domain using forestprep ad adprep.
This will going to update the schema to windows 2012 R2 Level. Please note that I am going to promote this Server to DC. I just want to extend the schema
Step 2 -) Install Windows 2016 server as member server ( Server B ) and prepare forest and domain using forestprep and adprep
This will extend the schema and after that I am going to promote this Server to DC
My question actually is this : I think this will work but please let me know if i need to promote Server A to DC so that it became 2012 DC or I cdont have to promote it DC
and pls read the question carefully as most time I can genric copy past answer from net.
